From the Fault Tree Analysis (FTA) for Arria 10 PCIe Link Up Issue

https://community.intel.com/t5/FPGA-Wiki/FTA-PCI-express/ta-p/735993, I believe you are at Is rx_std_signaldetect asserted (Hypothesis 4). Can you try the suggestions in FTA_Table_View (No 4)?


If the suggestions in the FTA are not helpful, could you try to run at lower speed and see if this is a problem running at Gen3?


Thanks

Best regards,
